Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

A new recipe for gravity could help solve some of the universe's greatest mysteries. It suggests that the concept of "quantum ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Scientists have determined a way to measure gravity on microscopic levels, perhaps bringing them closer to forming a theory of "quantum gravity" and to solving some major cosmic mysteries. Quantum ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

Newton's theory of gravity posited instantaneous gravitational attraction, successfully predicting planetary orbits. Einstein's special relativity challenged this, necessitating the development of ...
